Well, I went with a Transfiguration Temper W. Other candidates were: Allaerts, Colibri, Airy 3, Magic Diamond, and Shelter 90x. My decision was based on four points:
1.) It appeared to have the best build quality. And the fit and finish turned out to be absolutely stunning in the flesh.
2.) It employs the newest design thinking and technology -- a yokeless design using double ring magnets and a special mu metal coil former which increases sensitivity by 30dB.
3.) It had reasonable output voltage (0.5 mV), good compliance (not too high or too low) and nominal loading requirements. There is nothing about this cartridge that is non-standard or requires special accomodation in tonearm or electronics.
4.) I could obtain one new for a very attractive price.
In addition, it requires only a short (30 hour specified) break-in period, due no doubt to the new generation rubber suspension material, which is unaffected by temperature.
So far (one afternoon/evening-worth) , it's performance is
astounding compared to my Frog Gold, but I was expecting as much. I'll write a proper review after 50 or 60 hours. Thanks for all the input -- Raul, Rushton, and Speedy.
